Jenkins Ec2 Fleet plugin - How to run jobs in diferent spots?

Question

We recently installed the EC2 Fleet plugin in jenkins and we have a problem when trying to use it in a pipeline. We have a pipeline that build 2 diferent jenkins jobs. Each job have to be run in a different spot, so in total, three spots should be created: One for the pipeline, and two for the jobs. The problem here is that the two jobs queues in the same spot the pipeline is runing on... Have anybody dealt with this problem before? Here is the example pipeline:

stage('carga proyecto1'){
    
    
        
    parallel(
        JOB1:{
        def job = build job: 'Plantilla Kettle'
        },
    
        JOB2:{
        def job2= build(job: 'Utils/Plantilla Qliksense', parameters: [string(name: 'project', value: 'Test')])
        }
    ) 
    
     
     
    
    }
